I have an upcoming stay that was booked under some massive corporate program that isn't eligible for credit. Is there an easy/inexpensive way to apply some kind of upgrade that would get me the nights & points?
Convince your corporate overlords to allow employees to pay with their own personal credit cards and get reimbursed by the company.
Most hotels under any flag will still give a negotiated rate under such an arrangement depending on the number of people being brought to the hotel, but if it's a mass-bill arrangement, no rewards for loyalty program members.
